Insulated water bottles are undoubtedly the king of all drinking vessels. Made of supreme food-grade stainless steel, they are BPA-free, resistant to puncture, oxidization, hence the most eco-friendly, durable, and reliable. What makes insulated water bottles truly excel lies in its capability in retaining heat and maintaining the temperature of its content for an extended period of time.
The key to insulation is to stop or slow the spread of heat, which relies on a vacuum layer between the double walls of a container. Vacuum is crucial in blocking the traffic of heat, keeping the inside of the bottle totally insusceptible from the outside elements.
Understanding the Secret to Heat Transfer: Conduction and Convection
First, let’s decipher the secret to temperature change before cracking how insulated water bottles work. Molecules, the simplest unit of chemical substance, make up the things around us. They are present in the air as well as physical objects. When molecules from different materials come into contact with each other, conduction occurs. Heat is shifted from the areas with greater kinetic energy to those with less.
Thermal transfer occurs when the molecules from one material are exposed to other molecules that carry a varied kinetic energy. This exchange of energy goes on until the two temperatures reach an equilibrium.
Another form of heat transfer is convection that takes place in liquids and gases through the movement of molecules. Heated molecules tend to rise above colder molecules, pushing colder molecules closer to the heat source. This process continues until all the molecules reach a constant temperature. That’s why all quality insulated water bottles come with a good sealing lid or cap to prevent convection from compromising the temperature in your bottle.
A Bottle inside A Bottle
With a double wall construction, an insulated bottle can be broken down into two vessels separated by vacuum. This triple layer (inner, vacuum, and outer) structure makes sure the inside and outside of the bottle are non-interactive. With nothing to conduct or convey heat, vacuum sleeve is totally insulated from the outside heat.
As conduction and convection are annulled with the vacuum chamber, the last form of heat transfer comes from radiation. Anything with a temperature greater than zero emits some energy as radiation, although the amount is mainly subject to the temperature. There is no way to completely stop heat loss by radiation. It’s tested that the amount of heat loss can be drastically reduced by lining the inside of the vacuum chamber with a highly reflective coating, such as a thin layer of copper.
Buzio water bottles feature its signature ThermoArmour technology, with an extra layer of copper coat on the vacuum chamber to prevent radiation. That’s why Buzio water bottles boast of exceptional 48 hour keep cold and 24 hour keep hot capability.
BUZIO Vacuum Insulation Technology
100% food-grade stainless steel sprayed with fine powder coat for a non-slip, sweat-free finish
BPA-free 100% food-grade stainless steel without any synthetic lining that won’t react with your beverages or leach any hazard into your drink
Copper Lining on the Exterior of the Inner Vessel
30% more thermal insulation thanks to minimized radiation than that of same type vacuum insulated bottle
The buffer layer to cut off the touch of inner layer and outer shell, minimizing heat transfer
The content inside your bottle won’t warm up or cool off for up to 48 hrs / 24 hrs
The Making of the Most Robust Insulated Water Bottle
Since there is no counterbalancing pressure from within, vacuum insulated chambers or containers have to withstand the pressure from outside, hence they should be constructed from materials with superior rigidity and strength. That’s why only the top-grade stainless steel makes the cut.
Besides from being robust and puncture resistant, stainless steel are the most recycled material on earth, making it the greenest choice for hydration. Compared with glass, it won’t break, and is more compact, light-weight, and portable. It’s no exaggeration to say that insulated stainless steel water bottle is the must-have survival gear for life in the wild.
With vacuum as the armor of heat, insulated stainless steel water bottles sustain the temperature of your drink for the longest, saving much energy in chilling or reheating, making it the most energy-efficient and cost-effective container.
Buzio One-of-a-Kind Powder Coat
Besides the impeccable making on the inside, the exterior of Buzio bottles is also immaculately finished. With a special powder coat on every bottle treated with thermal bonding process, they are built more resistant to scratches, chipping, and color fading. In general, powder coats are superior to paints. They can be applied and layered up generously so that they last longer. Plus, their textured touch is exceptional, provides extra grip and does not sweat.
You can find a wide array of high quality insulated bottles to go with your hiking and lifestyle. Buzio carry diverse sizes with variations on colors, handles, lids, mouthpieces, and accessories. Select one that most accurately embodies your personality. Hydration is essential, but who says it can’t be fun?
